Smallmouth bass and dusky shiners in high velocity closeupIn this short clip a sunfish is using the camera housing for cover (perhaps as hydraulic refuge). In the background are dusky shiners and a smallmouth bass (Micropterus dolomieu). We did not measure velocity, but shooting this was very difficult, and I estimate it was approaching two feet per second. The camera housing is close to the fish, which are interacting with the turbulence it causes.
